From the 4 and 5 is a close to the inner wall leaning multi-part air chamber packaging film can be seen, wherein in 4 the surface image is shown before inflation and in 5 the cross-sectional image after inflation is shown.

The multi-part air chamber packaging film has an inflation passage 3 , an air chamber 4 , an air intake muzzle 2e , an air passage 5 , a branch air passage 6 , and an opening mouth 8th on.

The inflation passage 3 is the space of which two outer films joined by heat sealing 2a and 2 B is formed. It can also be made of two inner foils bonded by heat sealing 1a and 1b be formed. The inflation passage 3 includes the inflation mouth 31 , which serves as an inlet for the outside air.

Multiple main air chambers 4 are made of two external films bonded by heat sealing 2a and 2 B formed and can store air. Here are the multiple main air chambers 4 parallel next to one another laterally of the inflation passage 3 , Each air chamber is manufactured by heat sealing and serially connected multiple air chambers 40 educated.

Several air inlets 2e be between the inner foil 1a and an outer foil 2a or 2 B formed by heat-resistant elements 1c on a side surface of the inner film 1a are applied and with by heat sealing with the outer film 2a or 2 B are connected. They serve to connect the inflation passage 3 with the air chamber 4 ,

Multiple air passages 5 close to the air intake mouths 2e on and between the inner foil 1a and an outer foil 2a or 2 B formed by heat-resistant elements 1c on a side surface of the inner film 1a are applied and not by heat sealing with the outer film 2a or 2 B are connected.

Multiple branch air passages 6 close to the air passages 5 on and between the inner foil 1a and an outer foil 2a or 2 B formed by heat-resistant elements 1c on a side surface of the inner film 1a are applied and not by heat sealing with the outer film 2a or 2 B are connected.

Several mouths 8th are located on the inner foil, each opening mouth is located at the end of each branch air passage.

According to the illustrated configuration of this invention, heat-resistant members become 1c applied to a side surface at equal intervals, wherein the distance of the heat-resistant element 1c between the top and bottom with the length of the air chamber 40 is identical and the distance between left and right with the width of the air chamber 40 is identical.

During inflation blows into the inflation opening 31 entering outside air the inflation passage 3 on, eliminating the inner liner 1a and an outer foil 2a or 2 B be pulled apart and the air inlets 2e open (In another configuration, two outer films are also used 2a and 2 B pulled apart and open the air inlet openings 2e .). If the outside air enters the air passage 5 In, a part of the outside air flows into the branch air passage, and passes over the opening mouth 8th at the end of the branch air passage 6 further into the air chamber 40 a, which is thus inflated and thus expands. Along the air passage 5 another part of the outside air flows into the other branch air passage 6 one. The air passes over the mouth of the mouth 8th at the end of each branch air passage 6 further into the other air chamber 40 which are inflated thereby and expand accordingly.

After inflation of each air chamber 40 the internal pressure of the outside air of each air chamber pushes 40 the inner foil 1a close to an outer foil 2a or 2 B and closes the air inlet 5 , whereby each air chamber 40 is blocked. Thus, the outside air in the air chamber 40 do not escape and an air-lock effect is achieved. In case of damage to any air chamber 40 can be avoided by the configuration according to the invention that the outside air from other air chamber 40 flows out, so that vibrations are further absorbed and the buffer protection effect is maintained.

Further, the air pressure in each air chamber 40 identical, so that when inflating the air pressure in the air chamber 40 which are closer to the inflation passage 3 is not first the air intake 5 closes and it is thus avoided that the rear air chamber can not be inflated. That's why all the air chamber 40 be inflated simultaneously after the configuration of this invention. This can not only increase the rate of inflation, but also save further costs.

In the above-mentioned inflation passage 3 standing at an air intake muzzle 2e connected, can also have multiple air inlets 2e be connected. Every air chamber 40 can with an air passage 5 or several air passages 5 be connected. In addition, all air chambers 40 interconnected and use an air passage 5 or several air entrances in common. Furthermore, the size of the two outer films 2a and 2 B with the inner foil 1a be identical, or the length of the inner film 1a can be shorter than the two outer films 2a and 2 B his and the upper side of the inner film 1a may be on the upper side of the outer film 2a and 2 B align. And if the length of the inner film 1a shorter than the two outer films 2a and 2 B is, may be an end of the inner liner 1a that from the inflation passage 3 far away, first by heat sealing with an outer foil 2a or 2 B get connected.

From the 6 and 7 are two close to the inner wall leaning multi-part air chamber packaging films can be seen, wherein in 7 the cross sectional image after inflation is shown while in FIG 6 the surface image is shown before inflation.

The multi-part air chamber packaging film has an inflation passage 3 , an air chamber 4 , an air intake muzzle 2e , an air passage 5 , a branch air passage 6 and an opening mouth 8th on.

The inflation passage 3 is the space of which two outer films joined by heat sealing 2a and 2 B is formed. It can also be made of two inner foils bonded by heat sealing 1a and 1b be formed. The inflation passage 3 has an inflation opening 31 , which serves as an inlet to the outside air.

Multiple main air chambers 4 are made of two external films bonded by heat sealing 2a and 2 B formed and can store air. Here are the multiple main air chambers 4 parallel next to each other on the side of the inflation passage 3 , Each air chamber is made by heat sealing and serially connected to multiple air chambers 40 educated.

Several air inlets 2e be between the two inner foils 1a and 1b formed by heat-resistant elements 1c between the inner foils 1a and 1b be applied and by heat sealing two inner foils 1a and 1b be connected to each other. They serve to connect the inflation passage 3 with the air chamber 4 ,

Multiple air passages 5 close to the air intake mouths 2e on and between the two inner foils 1a and 1b formed by heat-resistant elements 1c between the inner foils 1a and 1b be applied and by heat sealing two inner foils 1a and 1b be connected to each other.

Multiple branch air passages 6 close to the air passages 5 and are between two inner foils 1a and 1b formed by the fact that the heat-resistant elements 1c between two inner foils 1a and 1b be applied and by heat sealing two inner foils 1a and 1b be connected to each other.

Several mouths 8th lie on an inner foil 1a or 1b , or at the same time on two inner foils 1a and 1b at, each of which mouth opening 8th at the end of each branch air passage 6 lies.

According to the illustrated configuration of this invention, a heat-resistant member 1c between two inner foils 1a and 1b introduced at equal intervals, the distance of the heat-resistant element 1c between the top and bottom with the length of the air chamber 40 is identical and the distance between left and right with the width of the air chamber 40 is identical.

During inflation, it flows in the inflation mouth 31 entering outside air in the inflation passage 3 and expand it, leaving the inner liner 1a and an outer foil 2a or 2 B be pulled apart and the air inlets 2e open (According to other configuration, also two inner foils 1a and 1b pulled apart, or an inner film 1a / 1b and an outer foil 2a / 2 B , and thus open the air intake ports 2e .). If the outside air enters the air passage 5 In, a part of the outside air flows into the branch air passage and the air passes over the opening mouth 8th at the end of the branch air passage 6 further into the air chamber 40 which inflates and expands. Along the air passage 5 another part of the outside air flows into the other branch air passage 6 one and the air passes over the opening mouth 8th at the end of each branch air passage 6 further into the other air chambers 40 which are thereby inflated and expanded.

After inflation of each air chamber 40 is the internal pressure of the outside air of each air chamber 40 on the inner foil 1a , so close to an outer film 2a or 2 B lies and the air inlet 5 covered and thereby each air chamber 40 concludes. In this way, the outside air in the air chamber 40 do not escape and an air-lock effect is achieved. When damaging any air chamber 40 The configuration according to this invention can avoid the outside air from other air chambers 40 flows out, so that vibrations are still absorbed and the buffer protection effect is maintained.

Out 8th is an embodiment in which two layers are provided on the walls of the multi-part air chamber packaging film, can be seen. 8th shows the cross-sectional image after inflation.

When each air chamber is expanded by inflation, the internal pressure of the outside air of each air chamber is 40 on the two inner foils 1a and 1b and these are not against the outer film 2a or 2 B so that the kind of two layers are formed on the walls of the multi-part air chamber packaging sheet. It will not be the two inner films 1a and 1b to the outer foil 2a or 2 B laid out laterally; otherwise, the configuration is the same as two layers of a multi-part air-chamber packaging film which closely follow the inner wall.

In the above-mentioned inflation passage 3 that with an air intake muzzle 2e connected, can also have multiple air inlets 2e be connected. Every air chamber 40 can with an air passage 5 or several air passages 5 get connected. In addition, all air chambers 40 connected to each other so that they have an air passage 5 or multiple air inlets can share. Furthermore, the size of two outer films 2a and 2 B with that of two inner foils 1a and 1b be identical, or the length of two inner foils 1a and 1b can be shorter than that of two outer films 2a and 2 B his and the upper side of two inner foils 1a and 1b on the upper side of the outer film 2a and 2 B align. And if the length of the two inner foils 1a and 1b shorter than the two outer films 2a and 2 B is, can be an end of the two inner foils 1a and 1b that from the inflation passage 3 far away, first by heat sealing with an outer foil 2a or 2 B be connected and thus create the closure state.

From the 9A and 9B the separable multi-part air chamber packaging film is apparent, wherein 9A the diagram (1) before inflation, while 9B the graph (2) before inflation is.

At the junction between each column of air 4 and every air chamber 40 becomes a cutting line 9 introduced, and along the cutting line 9 is cut so that each air chamber is separable from each other. Furthermore, the cutting line 9 be formed as a stork line in a multi-part air chamber packaging film, so that the user just along the cutting line 9 the packaging film tear this and every air chamber 40 can use individually. By using the cutting line, a large amount of individually usable air chamber packaging films can be produced.

At the inflation passage 3 can also be a cutting line 9 be used. After inflation can be cut along the cutting line so that the air column 4 is separated at two ends of the inflation passage. Thus, the production of air columns 4 be doubled.

Even though the technical content of this invention with embodiments described above is shown, this is not limited thereto.
